Working Principle

The LNK413LG utilizes a buck-boost circuit to generate a precision current regulated output. In operation, it responds to a pulse-width modulated (PWM) signal from a microcontroller and generates a regulated LED string current of up to 1A (at 25°C ambient temperature) with a 63V output voltage range.The product utilizes a low-dropout (LDO) linear regulator to stabilize the LED string current. The regulator also provides for loop regulation, current-share regulation, voltage-share regulation, and soft-start/stop capabilities. The LNK413LG also offers improved efficiency, with an overall system efficiency of up to 90%.The product also includes a system health monitor that can detect open or short circuit faults and provide an interrupt signal to the microcontroller.

Conclusion

Linear Technology’s LNK413LG is a high-voltage, highly integrated Flyback Controller for controlling constant-current LED strings. The product is suited to a variety of applications, including general lighting, backlighting, decorative lighting, and higher power applications. It utilizes a buck-boost circuit to generate a precision current regulated output and a low-dropout linear regulator for loop regulation, current-share regulation, and voltage-share regulation. The overall system efficiency of the LNK413LG is up to 90%. The product also includes a system health monitor and provides for reliable, consistent dimming control.
